When you want to send a message - like a press release - you send it when it's going to likely get picked up. Early AM or early afternoon before assignments are given out. If you do not want much news coverage then send a press release out 6:00 pm on a Friday afternoon. When this shooting happened (around 8:00 am) most local news stations were having their assignment meeting. The terrorist snipers have timed their killings/woundings to get the maximum exposure. I'm unsure about the precise time the first attacked happened in Montgomery county.
Where were they all weekend???
Maybe keeping up appearances within a community.
Maybe switching motels, cars. Folks see them going to work in the AM and coming home in the evening....Nothing unusual (except they don't really have a job or free lance).
I think the last two shots, (Friday & Monday) which were not "head" shots were by a "second" sniper and thus the difference in the "perfection" of the early "kill" shots. The second guy may be on the run because he may have been seen by the boy so we'll likely see "kills" again and the first "expert" sniper take over again or a new "third" sniper.
